Designed and implemented a distributed, virtualized highly fault tolerant network cluster
for storing block data over an ip network.
High performance, minimal lock design written in C++ delivers extremely high iops per
watt, running at full line speed across the cluster.
No single or dual point design given sufficient hardware.
Designed a hybrid epidemic, eventually consistent gossip type protocol.
Implemented both 2PC and an unblockable enhanced three phase commit engine.
Implemented view consistent message delivery.
Designed a super fast custom flash journal to allow complete recovery from process fault.
Implemented a live production cluster upgrade and downgrade mechanism.
Designed patentable sophisticated permuted data layouts.
Implemented command line parser and table output administration tool.
Implemented base iSCSI with CHAP MD5 authentication, and SCSI block specs. Stable
against numerous Linux, Windows, and Mac initiators.
Designed and implemented a randomized simulation test system.
Evaluated, built, and tested several generations of hardware platforms to deliver working
stand alone and enterprise grade rack mount solutions to clients.

 Tested and isolated IP SAN communication errors in the first generation product.
 Developed high performance two stage write cache for an IP SAN, improving iop
performance twenty fold. This involved sophisticated memory mangement techniques
and highly tuned data structures for manipulating hundreds of megabytes of data.
 Used PCI and IDE bus analyzers and scopes to isolate problems or prove cache
functionality.
 Developed custom performance testing and analysis tools in addition to using commonly
available profilers.
 Designed, assisted in the development of, and rigorously tested the world's most
sophisticated NVRAM device. The device uses SDRAM, NAND FLASH, an EEPROM,
a Xilinx FPGA and PROM, supercaps, and a PCI interface to secure cache data in the
event of a transient failure such as loss of system power or crashed software.
 Developed an NVRAM linux device driver and api.
 Performance tested various embedded platforms for a san router project codeveloped
with Crossroads.
 Read entire SCSI-3 and iSCSI specs and removed various defects from SCSI/iSCSI san
drivers.
